Alpha 3D Model Rocket

prusaprinters

<p>This is my tribute to a classic Estes kit. The Estes Alpha III was one of the first rocket kits I built as a kid. While this isn't an exact copy of that kit, it is quite similar appearance.</p> <p>You can either print just the nose cone and fin canister and use standard BT-50 body tube (6" long) or you can print the body tube model using 'vase mode' (single wall spiral w/ no top or bottom).</p> <p>You can use either ABS or PETG for printing. I used ESun PETG translucent orange for my 'full print' version. For ABS I've found the FoxSmart ABS to be a good and cost effective filament. The version built with a standard body tube has red FoxSmart ABS for nose cone and fin canister. The 'thick' version of the fin canister has slightly thicker fins for more durability.</p> <p>Try an A8-3 for first flight, B6-4 for second flight.</p> <p>Launch video: <a href="https://youtu.be/lyxZVnFooGs">https://youtu.be/lyxZVnFooGs</a></p> <p>Since this is a scratch built rocket, always perform a swing test of the fully prepped rocket before flying. Add weight to nose (clay) until swing test is successful.

Use a brim if you are concerned with bed adhesion. I used a 5mm brim when printing ABS. I also found that for ABS, I had best results printing multiple objects in one job, since this gives the ABS a bit of time to cool without need of the fan.</p> </p></p></p> Category: Vehicles
